Re: PCBs for Spectrum Clones

That RC6502 Apple 1 Replica PCB looks very familiar... just like the one that I have recently been buying parts for...

Re: PCBs for Spectrum Clones

Not that I have been paying much attention recently, but last year (or was it 2018) there was a moan about there being no published schematic for the Just CPC PCB. I recall on another forum, a member having difficulty fault finding it when it did not work.

Re: Using more than 64k on the MTX

I suspect that part of the reason that there is little software making use of more than 64K is that there were very few machines back in the day with more than 64K to run the software on. A chicken and egg situation. Same problem with a lot of 80s micros. There is not much software from back then t...

Re: Another Home-Brew - Z180

You need some thin wire or thread to go via holes in the board and the mask to help hold everything in the correct place. Best if you can manage this at four corners or equivalent. The hole size for the thin wire or thread should be only big enough for the wire/thread to pass through, otherwise ther...

Wanted: unused or scrap boards / PCBs

My niece is doing an art project and is after some unused or scrap boards / PCBs to cut up and use in her project. Ideally without any large components fitted. So either defective depopulated boards or unused boards (e.g. where there is a layout or track design error or manufacturing problem). Howev...
